Abstract (en)
[origin: EP0753463A1] An anti-backoff, removable closure for connecting a manually actuated liquid dispenser to a container includes a closure cap (11) having internal threads (14) for mating engagement with similar threads (13) on the outside of the container neck finish (12), both the cap (11) and the neck finish (12) having mutually engageable ratchet teeth (26,17) mechanically retaining the closure to the container. The teeth (26) inside the cap each have a trailing face (28) lying in a plane sloping in a loosening direction of the cap relative to the central axis of the cap for producing a camming action between the cap teeth and the neck finish teeth, tending to cam the cap off the container in response to closure unthreading rotation. <IMAGE> <IMAGE>
